Abstract

L'invention concerne un embrayage à griffes (10A) comprenant : une pièce d'engrenage (20) pourvue d'une pluralité de dents (22) formées sur un périmètre externe pour constituer une ligne de dents (21); et un manchon (30) pourvu d'une pluralité de dents (32) formées sur un périmètre interne pour former une ligne de dents (31) s'engrenant avec la ligne de dents (21) de la pièce d'engrenage (20). La position de l'embrayage à griffes (10A) est changée entre une position enclenchée et une position désenclenchée, par le déplacement du manchon (30) dans le sens d'un axe (CL). Une partie saillante (34) faisant saillie dans un sens circonférentiel est formée sur au moins une dent (32a) du manchon (30) de sorte qu'une partie renfoncée (35) soit formée sur ladite partie saillante (34). Au moins une partie de la dent (22) de la pièce d'engrenage (20) est accueillie dans la partie renfoncée (35) de sorte qu'au moins ladite partie de la dent (22) de la pièce d'engrenage (20) chevauche sur ladite dent au moins (32a) du manchon (30) lorsque les lignes de dents (21, 31) s'engrènent.
